Apache ‘Eyes’
Pass Million-Hour Mark

During an event Thursday, August 8, 2013 at Lockheed Martin’s
facility in Orlando, company officials joined
with representatives from the U.S. Army, Boeing’s Team Apache
and operators to exalt the modernized target
acquisition designation sight/pilot night
vision sensor (M-TADS/PNVS) topping 1 million
flight hours.

EVANS
Capacitor Powers Arrowhead M-TADS/PNVS with
Capacitor Banks

The Evans Capacitor Company has won multiple
contracts from Lockheed Martin Missiles and Fire
Controls in Orlando, FL, to supply capacitors
for production of the Apache Arrowhead
(M-TADS/PNVS) Program.

Evans supplies two
specially built and packaged capacitor banks
for the system. It has provided capacitor
banks for approximately 1,300 Arrowhead ship
sets since 2005. Accumulating 1,000,000 hours
on the system, represents over 20,000,000
capacitor flight hours in Apache without a
single reported capacitor problem.

In April, 2006, The Evans
Capacitor Company was the recipient of the
Lockheed Martin “Supplier Excellence Award”
for the Arrowhead Program. Lockheed Martin has
also recognized Evans with a a a "Small
Business of the Year Award" and the
prestigious "Platinum Preferred Supplier"
award.

Excellence Award” for the

Capacitor banks for the
Arrowhead system use Evans Hybrid® Capacitors,
completely wired and packaged in rugged
aluminum housings, as line replaceable
modules. One bank is rated at 50V and 144,000
µF, utilizing six THQ3050243 capacitors in
parallel. The other bank is rated at +/- 135V
and 1,100 µF, using three THQ125332 capacitors
in series.

THQ3 capacitors utilize Evans
patented Hybrid® Capacitor technology, which
provides very high power density compared with
other tantalum capacitors. Hybrid Capacitors
have a tantalum pentoxide dielectric, in
conjunction with a Ruthenium oxide cathode,
providing high single cell voltages (high
power density for pulse applications) and high
capacitance (high energy density for power
back up applications).

A 15-year-old firm in East
Providence, RI, the Evans Capacitor Company
holds US Department of Energy and US Military
quality and performance ratings for the design
and manufacture of capacitors, which are
frequently specified for mission critical
applications. David Evans, its president,
holds 15 patents.
